Ken Rockwell analiza la Sony A7R III y además nos facilita el User Manual

¿ La mejor Sony hoy en día ? Para mi que si.
¿ La mejor cámara hoy en día ?, Jo, tu, menuda pregunta.

Era inevitable, era solo cuestión de tiempo, tarde o temprano tenía que suceder.

El bueno de Ken Rockwell ha probado la Sony Alfa 7R III y nos lo cuenta con su habitual estilo en un artículo de una página larguísima con imágenes de la maquinita a tamaño XXXXXXL que os permitirán observar sin problema la estructura molecular de la carcasa.

Si, si, no sufráis: en las muestras también sale su famosa palmera, de noche, pero sale.

Particular interés tiene la secuencia de imágenes de la modesta mansión habitual con hogar de leña y reloj a todos los ISO’s, donde los detallistas os podréis deleitar con los más minúsculos detalles del hogareño paisaje a ISO’s bajos y los ruidosos os podréis asombrar aún más al contemplar sorprendidos como hasta 6400 ISO la cosa se mantiene casi absolutamente igual. Se empieza a ver algo de grano solo a partir de 12.800 ISO, pero muy poco. ¡¡¡ Que barbaridad !!!

Juro por lo más mundano o prometo por lo más sagrado que en mi próxima reencarnación seré Sonysta. Para entonces espero que Sony haya comprado a Nikon y a Zeiss, y así tendremos cuerpos serios y objetivos Otus, pero con AF.

Por poner algo, os pongo lo habitual para esta WEB.

New since the A7R II

• 10 FPS, up from 5 FPS.
• Two card slots.
• Bigger NP-FZ100 battery lasts about 1,500 shots in normal shooting (CIPA rated 530 single shots; old A7R II was rated only 290 shots).
• Three memory recalls on the top mode dial, with four more presets almost as easy to recall.
• New thumb-nubbin controller on rear.
• Touch screen, but only for very basic AF point selection.
• 425 contrast AF points, up from 25.
• Ability to shoot-through flickering lighting.
• Two separate AEL and AF-ON buttons, instead of just one button with a selector lever as on A7RII, A7SII, A7II and A7.
• C3 button moved to left side of camera; it’s on the right on A7RII, A7SII, A7II and A7.
• Higher resolution electronic viewfinder.
• In-camera 5-axis sensor-shift stabilization now claims 5.5 stops improvement.
• Weird «Pixel Shift» mode uses sensor-shifting to make four sequential scans of a fixed image that, if combined later in your computer with Sony’s «Imaging Edge» software, might improve resolution. This only works on a tripod and only with rigid subjects; if anything moves even slightly you’ll get weird color fringes.
• 14-bit raw.
• Shoots 4K video using the entire 36mm width of the image sensor.
• Uncompressed 4K HDMI output.
• XAVC S high-bitrate video formats for 60~100 MBPS video.
• Under- and over-crank video from 1 FPS to 120 FPS, MOS (without sound).

Good:

• Magnificent electronic finder: always big, bright, sharp and wonderful in any light. Super-bright in daylight, and dims perfectly indoors and at night.
• Hybrid AF system uses phase-detection for speed and contrast detection for ultimate precision and accuracy.
• Battery life seems almost unlimited.
• Solid mostly metal construction.
• Even the regular mechanical shutter only moves at the ends of exposures. There’s never any need for a special vibration-free mode; it always works this way. Suck on that, LEICA!
• Excellent high ISO performance.
• Facial recognition works well, but only after you find it and turn it on.
• In-finder 2-axis level works great for keeping horizons and vertical lines as they should be.
• In-camera, as-shot automatic lens vignetting, lateral chromatic aberration and distortion correction.
• Almost any lens of any brand or age can be adapted to work – but with no lens corrections.
• Stereo microphone built-in.
• 3.5mm powered mic and headphone jacks.
• Can extract stills from video, in-camera after it’s shot. In other words, shoot 4K video and you can pull-out 8MP stills shot at 30 FPS.
• Bluetooth & NFC.

Bad:

• If you set it to record to two cards for backup as I do, and then remove one card or it fills, the camera stops shooting. It should just shoot to either card that has space, not leave you dead in the water.

Missing:

• Silent electronic shutter is a game-changer, but won’t work with flash. Flash sync speed is still only 1/250.
• No built-in flash.
• No auto brightness control for the rear LCD (but great auto brightness control for the electronic finder).
• No GPS.
• No shutter speed dial.
• No ISO dial.
• No square, 4:5 or 4:3 crops; 16:9 only.
• No way to back up the complete camera state as Nikons can do.
• No more 0.5 second image auto review option, just 2, 5 or 10 seconds.
• 4K video, but no 4K/60. So?
• Touch screen lets you select movie focus areas, but doesn’t work for setting the camera in the menu screens.
• No multi-frame noise reduction (just set a slower ISO and make a longer exposure for the same effect).
• No more swept panoramas (an iPhone does this better anyway).
• Three preset memory modes (good), but no way to set these to auto-update as you’re learning your new camera. The memories can only be saved manually.
